IMPROVEMENT IN LANTERNS.

Specification forming part of Letters Patent No. 118,576, dated August29, 1871.

To all whom 'it may concern:

Be it known that I, FREDERIC A. BALGH, of Hingham, in the county ofSheboygan and State of Wisconsin, have invented a new and usefulImprovement in Lanterns; and I do hereby declare the following to be afull, clear, and exact description of the same, reference being had tothe accompanying drawing, in which- Figure l. is an elevation of atubular lantern provided with my improvement. Figs. 2, 3, 4 representdifferent methods of operating my improvement. Figs. 5, 6 representdifferent ways ofsecuring the bottom plate upon which the lantern-globerests.

This invention relates to that class of lanterns known as tubularlanterns; and it consists principally in attaching the globe or glass ofthe lantern to the upper or sliding band by means of adjustable catchesor similar devices not depending upon frictional contact for theiraction, so that when the lamp is to be lighted it will not be necessaryto remove said globe, but only to raise the same by the movement thatraises the upper band, and at the same time make the globe easilydetachable from said band.

As tubular lanterns have heretofore been constructed the globe has onlybeen held in place by the upper band, and has been liberated when saidband was raised, so that in lighting the lamp it is necessary rst toremove the globe. This requires the action of both hands and iscorrespondingly inconvenient. Y By my invention the globe is attached tothe upper band, and when said band is raised the globe is raised withit, and the lamp may then be lighted by a match held in the other hand,and without the removal of the globe at all. It may sometimes happenthat the globe will t so snugly in the upper band that it will move upand down therewith. The variation in size of the glasses will alwaysrender this mode of securing by frictional contact unreliable, and I layno claim thereto.

The mechanical methods of attaching the globe to the band are various.They are, for convenieuce, required to be such that the globe may beeasily detached when it is required to remove it for the purposes ofcleansing or to replace it if broken.

That others may fully understand my invention, I will particularlydescribe it and some of the methods by which it may be employed.

which raises the said band.

Fig. l represents a tubular lanternwith my improvement, in which A isthe upper band, and B is the glass or globe. The upper band A isattaehed to the cap a., which slides upon the central flue b, and isdepressed and kept down by a spiral spring, c. The stirrup d serves todraw up the cap a, and band A in the manner shown in dotted lines in thefigure.

In the tubular lanterns, as heretofore constructed, when the cap andband are raised by one hand the glass or globe must be grasped by theother, or it will be liable to fall over.

In Fig. 1 the glass or globe is provided with a metallic band, C, placedaround said globe below the bead e, with which the glass is alwL ys provided, and the hooks D or their equivalents may be employed to attachthe band C to the band A, and thus secure the glass or globe in place,so that it will be raised by the same power This may be the mostconvenient manner of applying my invention to lanterns in the market orin use. In the course of manufacture, other means of attachment couldmore protably be employed, as, for instance, some form of thebayonet-joint, as shown in Figs. 2 and 4, or some form of hook-andeye,as shown in Fig. 3. The band Amay be cut and made to open, and by itselasticity clasp the top of the glass, or it may be secured by abindingscrew, spring-catches, or in Various other wellknown ways notnecessary to recapitulate here.

I am wel] aware that the glasses or globes of lanterns have heretoforebeen secured to the bands of the lantern-frame; but in all such cases,whether rigidly secured or detachable, the purpose has been to connectthe parts of the lantern by means ofthe glass. In my invention the glassforms no part of the frame, but is supported by it. I am also aware thatin the tubular lantern constructed without a sliding cap and band theupper part of the glass has been made cylindrical so as to slide withinthe stationary cap or upper band.

As the tubular lanterns on which this is animprovement have heretoforebeen constructed, the perforated diaphragm g at the bottom of the glassor globe has been retained in place entirely by the downward pressure ofsaid glass, and when said glass is lifted said diaphragm is liable tofall out of place. I therefore prefer to attach the same to the bottomof the glass B, so that when raised the cone E of the burner will `beHaving described my inyention, what I claimY n as newr 1sl. The slidingband A and globe B of a tubular lantern, in combination With adjustablecatches D, or similar devices not depending upon frictional contact fortheir action to secure said band and globe together, and yet render saidglobe easily detachable, as set forth.

2. The band A and globe B, in combination With the baud C and adjustablecatches or hooks D, for the purpose set forth.

3. In combination With a tubular lantern, the

globe B secured to the sliding band A by means of adjustable catches, asset forth, and the diaphragm g secured to the lower end of the globe B,as described.
